Install target

Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned aj-geddes/useful-ai-prompts at 3f5182cfd7.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill helps AI agents analyze and reduce the size of software bundles, such as npm packages or application builds. It identifies unnecessary dependencies and suggests specific strategies to minimize download times and improve performance.

When to use it

  • Reducing load times for web applications with bloated dependency trees.
  • Optimizing mobile app packages to fit within strict storage limits.
  • Lowering bandwidth costs for distributed teams or CI/CD pipelines.
  • Preparing large codebases for deployment on resource-constrained edge devices.

Key capabilities

  • Analyzes package manifests to detect unused or redundant libraries.
  • Suggests peer dependency management strategies to avoid duplication.
  • Recommends tree-shaking configurations and build optimizations.
  • Provides actionable steps to split monolithic bundles into smaller chunks.

Example prompts

  • "Analyze my package.json and list the top 5 largest dependencies that might be unnecessary."
  • "Suggest a strategy to reduce the size of my Next.js production build by at least 20%."
  • "Identify duplicate peer dependencies in this project and propose a resolution plan."

Tips & gotchas

Ensure you have access to your project's dependency tree before running analysis, as some tools require specific file structures. Be cautious when removing dependencies; always verify that core functionality remains intact after optimization.
